With HTTP you use high-level HTTP protocol(that works on top of a socket). It's session-less which means you send text request like <code>GET google.com</code> and receive text or binary data in return, after that connection is closed(in HTTP 1.1 persistent connections are available)

MSDN example:

<pre><code>public static void Main (string[] args)
{
 HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);
 HttpWebResponse response = (HttpWebResponse)request.GetResponse ();

 Console.WriteLine ("Content length is {0}", response.ContentLength);
 Console.WriteLine ("Content type is {0}", response.ContentType);

 // Get the stream associated with the response.
 Stream receiveStream = response.GetResponseStream ();

 // Pipes the stream to a higher level stream reader with the required encoding format. 
 StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);

 Console.WriteLine ("Response stream received.");
 Console.WriteLine (readStream.ReadToEnd ());
 response.Close ();
 readStream.Close ();
} 
</code></pre>

With sockets you go on the level lower and actually control the connection and send/receive raw bytes.

Example:

<pre><code>var remoteEndpoint=new IPEndPoint(IPAddress.Loopback, 2345);
var socket = new Socket(remoteEndpoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(remoteEndpoint);
socket.Send(new byte[] {1, 2, 3, 4});
</code></pre>

blocks|key|369826|text|HTTP是一种应用程序协议。这基本上意味着HTTP本身不能用于传输信息到远程端点或从远程端点传输信息。相反，它依赖于底层协议，在HTTP的情况下是TCP。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|369827|​|369828|📷|atomic|offset|length|369829|369830|如果你感兴趣，你可以阅读更多关于OSI+layers的内容。|369831|另一方面，套接字是大多数操作系统提供的能够与网络通信的API。套接字API支持从传输层到传输层的不同协议。|369832|这意味着如果你想使用TCP，你可以使用套接字。但是您也可以使用套接字通过HTTP进行通信，但是您必须根据HTTP规范(RFC2616)对消息进行解码/编码。由于这对大多数开发人员来说可能是一项艰巨的任务，因此我们在开发框架(如.NET)中也有了现成的客户端，例如WebClient或HttpWebRequest类。|style|CODE|369833|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/cff7946e47cac43f605709f2f740b31a.png|imageAlt|1|LINK|MUTABLE|url|http://en.wikipedia.org/wiki/OSI_model|2|http://www.w3.org/Protocols/rfc2616/rfc2616.html^0|0|0|0|1|0|0|0|G|A|1|0|0|3N|9|3X|E|1N|7|2|0^^$0|@$1|2|3|4|5|6|7|17|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|18|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|19|8|@]|9|@$G|1A|H|1B|1|1C]]|A|$]]|$1|I|3|C|5|6|7|1D|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|1E|8|@]|9|@$G|1F|H|1G|1|1H]]|A|$]]|$1|L|3|M|5|6|7|1I|8|@]|9|@]|A|$]]|$1|N|3|O|5|6|7|1J|8|@$G|1K|H|1L|P|Q]|$G|1M|H|1N|P|Q]]|9|@$G|1O|H|1P|1|1Q]]|A|$]]|$1|R|3|-4|5|6|7|1R|8|@]|9|@]|A|$]]]|S|$T|$5|U|V|W|A|$X|Y|Z|-4]]|10|$5|11|V|12|A|$13|14]]|15|$5|11|V|12|A|$13|16]]]]

HTTP is an application protocol. It basically means that HTTP itself can't be used to transport information to/from a remote end point. Instead it relies on an underlying protocol which in HTTP's case is TCP.

<img src="https://i.stack.imgur.com/kOrOP.png" alt="enter image description here">

You can read more about <a href="http://en.wikipedia.org/wiki/OSI_model" rel="noreferrer">OSI layers</a> if you are interested.

Sockets on the other hand are an API that most operating systems provide to be able to talk with the network. The socket API supports different protocols from the transport layer and down.

That means that if you would like to use TCP you use sockets. But you can also use sockets to communicate using HTTP, but then you have to decode/encode messages according to the HTTP specification (<a href="http://www.w3.org/Protocols/rfc2616/rfc2616.html" rel="noreferrer">RFC2616</a>). Since that can be a huge task for most developers we also got ready clients in our developer frameworks (like .NET), for instance the <code>WebClient</code> or the <code>HttpWebRequest</code> classes.

for two endpoints to be able to talk to each other they should both follow a set of rules. in computer these set of rules is called protocol.
for example for an endpoint like browser and for another like a web server they should both follow a set of rules or protocol called http to be able to communicate and trade information . so in the world wide web and this kind of communications only those who talk based on this http protocol could successfully talk to each other.
socket is just an endpoint. it could follow http protocol to come in a communication in www as a client requesting a page or it could act as a server listening to connections. or maybe it could follow another set of rules or protocols like ssh, ftp and communicate in other ways.
now in socket programming you could make a socket , bind it to an ip address and a port number to act as a port number and tell it to follow http , ssh ,ftp or whatever you want based on the communications that you want to use your socket for.

Socket programming is a kind of middleware, residing between the application layer and the TCP layer. It's able to carry anything present in the application layer; even HTTP data.

What is the difference between socket programming and Http programming? can anyone help please?
